SanDisk ExtremeFit – SanDisk’s ExtremeFit USB-C flash drive is selling for $99 for 512GB during the last day of Amazon’s Prime sale, down from $119. It’s tiny, fast for a flash drive, and rated plug-and-play by reviewers—while Prime Day runs June 23–June 26, 2026.
A coin-sized flash drive doesn’t usually land on a “worth it” shopping list—until the price makes the math work.
During Amazon’s last day of its Prime sale, the SanDisk ExtremeFit USB-C flash drive in 512GB is on sale for $99, marked down from $119. That’s $20 off the regular price, a 17% discount, and the deal won’t last much longer.
The ExtremeFit lives up to its name as one of the smallest external storage devices SanDisk sells in this category. In size, it’s described as about the same footprint as a mouse dongle. SanDisk also offers it in multiple storage configurations. ranging from 128GB up to 1TB—but the most practical option for many people is the 512GB model currently discounted to $99.
It’s also built for speed, at least for a drive you just plug in. After reviewing the ExtremeFit, it was found to be about as plug-and-play as it gets: it doesn’t require any particular software or formatting, and you simply insert it into a USB-C port for read speeds up to 400MB/s.
In everyday terms, 512GB is positioned as enough storage to equal “a whole other laptop,” with room for thousands of files. The storage list is specific: large 4K video files, image files, and renders—and “hundreds of hours” of full-length movies.
That’s why the ExtremeFit is being recommended for creators, professionals, and anyone who needs external storage but doesn’t have space for bulky—or more expensive—drives.
The drive also aims to reduce headaches across devices. The ExtremeFit is compatible with PCs, Macs, Chromebooks, and iPads, letting you use the same storage stick across different ecosystems. Still. there’s a tradeoff that comes with the size: the device is very small and could be easy to misplace. The advice given is simple—keep it with other designated tech items. or leave it plugged into your laptop’s USB-C port if you’re going to be using it regularly.
There’s another detail to the deal itself: the ExtremeFit sale is tied to Amazon’s Prime Day event. Amazon says the event launched Tuesday, June 23 and runs until Friday, June 26, 2026, and that it was shifted up from its usual July timeframe.
As for how the offer is being judged, the deal rating assigned is 3/5. The reasoning is direct: it’s 17% off, but it’s still sitting right at the $99 mark. The rating would improve if the price dipped below $99.
Prime deals can move quickly—Amazon notes that offers are subject to sell out or expire anytime, and new deals can keep replacing the ones that disappear.
